PATENT OFFICE.

The innovations forming the subject of the present invention have the purpose the connection of the wagons with the pulling rope, which is in continuous motion, in this way to cause that by a mechanical approach of the two clamping jaws against each other the intermediate rope is grasped and then by eccentric segments or their equivalents are self-sustaining, due to the movement of the pull rope in its longitudinal direction Compression caused and exactly proportional to the respective tension on the rope the clamping jaws, while the automatically triggered release of the Coupling at the same time the clamping jaws can be set back exactly in their middle position.

The new features are shown in various modifications on the accompanying drawings shown, in which the movement of the clamping jaws perpendicular to the rope axis either in verticaler, Figs. 1 to 16, or more horizontal Direction, FIGS. 17 to 33, takes place.

In Figs. 1 to 7, RR ^{1 designate} two rollers on which the pull rope Z rests, which rollers always secure the rope in the correct position to the clamping jaws KK ^l and which serve as guide rollers as soon as the device is disengaged, so the car to Has come to a standstill. The rollers RR ^{1 can be} raised or lowered by means of the two screws 5 S ¹ , thus giving the pull rope the correct height. KK ¹ denote the two clamping jaws, which are designed to press in the pulling rope so tightly that even with the strongest pull on the wagon on significant inclines, curves, large spans, etc.

slipping or sliding of the rope is not possible. Both clamping jaws are connected to one another on their rear side by a kind of toothing in such a way that a horizontal movement of the jaw K ¹ is also transmitted to the jaw K lying above and forces it to follow the movements, FIGS. 2, 3 and 7. The Upper jaw K is through the guide bar λτ, Fig. 3 and 5, with the slide B, which moves in the housing G, in connection. This guide bar χ prevents the jaw K from falling when the slide B is lifted, without affecting the horizontal movement of the same.

The slide B can be raised and lowered by the eccentric E and the hand lever H , Fig. 2 and 3. In the lowest position of the slide B indicated in the drawing, the lever H assumes its highest position and the clamping jaws KK ^{i have} so come far closer to each other, so that the pulling rope lying between them is gripped with a slight pressure. The clamping jaws are now pressed together further by segment T, FIGS. 2, 3 and 6, the periphery of which is shaped twice eccentrically, as has already been described for the sector used in the coupling devices for transport vessels, such as those in the patent No. 3761 are protected, is used. When using the Sector as described below, however, the jaws are pressed together completely automatically and in exact proportion to the respective pull on the rope. For this purpose the

lower jaw -Κ ' ¹ on segment T and the middle position of the latter corresponds exactly to the middle position of the clamping jaw. To secure the mutual position, the tooth-shaped projections ii, Fig. 2, which engage in corresponding depressions in the jaw, are used. The segment T rests on the bearing A located in the housing G.

The upper jaw K is supported against the segment D, which, in contrast to the segment T, has a centric surface; this segment D is mounted in the slide B , Fig. 2, 3 and 6. When the pulling rope is pulled, as a result of this combination the jaws K and K ^l, which are already in contact with the rope with a low pressure, make a slight movement in the direction of the rope movement Segments D and T must follow the movement, and the lower clamping jaw K 'is now pressed upwards through the eccentrically shaped surface of segment T , the stronger the more the rope is pulled, i.e. the more the clamping jaws are moved laterally . The effect of the device is the same in both directions of movement.

At the end stations of the cable car, the device is triggered automatically by hitting the lever H against an inclined plane. The lever H is thereby given a rotation of about 180 °, the eccentric E pulls the slide B with the jaw K upwards and releases the rope completely (see the dotted position of EDTm Fig. 2).

The two clamping jaws K and K ^{1 are} reset to the middle position while the device is being triggered by segment D. In the highest position of slide B , one of its two outermost ends hits the jaws C of housing G, FIG. 2, so that segment D is forced, during its upward movement, to adjust itself and thus both clamping jaws exactly to its central position, FIG. 2.

The locking bar L is used to lock the clamping jaws K and K ¹ in the middle position. In its lowest position, this occurs between the two ^{attachments P located on the lower jaw AT 1} and thus prevents horizontal displacement of the two clamping jaws, FIGS. 3, 4 and 7 .

The upward and downward movement of the bolt L is caused by the two pins MM ¹ , FIG. 4, located on the eccentric E , which occur against the nose O of the bolt L when the eccentric is rotated. The effect of this part of the apparatus manifests itself in the following way:

When the carriage arrives at the end station, as already described, the device is uncoupled by turning the lever H, whereby the slide B is lifted with the jaw K and the latter in connection with the other jaw K ¹ is forced through the segment D, return to the middle position. This case will occur shortly before the lever H reaches its lowest end position, and at this moment the pin M ¹ then strikes against the nose O of the bolt L, whereby the latter is pressed downwards between the shoulders PP of the clamping jaw K ¹ , FIG. 4 Both clamping jaws KK ¹ are now held in their middle position by the bolt L until the device is re-engaged, the lever H has almost reached its highest end position and the clamping jaws have already clamped the pull cable with little pressure. At this moment, shortly before the lever H reaches its end position, the pin M steps under the nose O, lifts the latch L and thus releases the two clamping jaws, which can now move freely in the horizontal direction.

t denotes the cover for the upper part and r the cover for the lower part of the housing G. The pin q in the cover r of the housing, FIGS. 2 and 3, serves to connect the lower jaws to the housing. For this purpose, the jaw K ^{1 is provided} with the inclined recess ρ ρ , in which the pin q slides.

Fig. 5 shows the apparatus brought by the flat iron bracket bb in a fixed connection with the carriage hanger, while in Fig. 3 the housing of the apparatus is provided with a pivot Q which can move in a bearing body U attached to the flat iron bracket b . After removing the screw w and the cover V , the apparatus can be removed from the bearing body U. While the construction shown in Fig. 5 will be used for horizontal or slightly inclined tracks, the arrangement shown in Figs. This construction offers the advantage in this case that the apparatus always adjusts itself automatically according to the inclination of the pulling rope, and the latter can never be stressed in an unfavorable way.

In FIGS. 8 to 12, a modification of the above-described arrangement is shown, in which the changes only apply to the use of longer clamping jaws KK ¹ and, accordingly, two segments DD respectively. TT refer. The latter two rest in the common bearing A, to which the plate Y provided with the pin q is attached. This pin q slides again in the slot-shaped recess ρ of the lower one

Jaw K ^l and thus serves the same for guidance. The purpose of the latter arrangement is to ensure the exact distance between the bearing A and the jaw K ¹ even if, when the jaw K 'is worn, it should be necessary to lift the latter under the bearing A by means of sheet metal strips.

13 and 14 represent a simplified arrangement of the apparatus illustrated in FIGS. 1 to 7. In this apparatus, the lower clamping ^{jaw K 1} moves on a horizontal sliding surface g of the housing G, while the upper jaw K is formed by the double eccentric shape Segment T is pressed down. The connection of the upper jaw K to the slide B is effected by the pin ^ ¹ fixed in B and the slot p ^l located in the jaw K.

Figs. 15 and 16 be a general front and side view of the assembly of this universal - clamping coupling apparatus, the housing, as in Figure 3, with the pivot Q, wherein U in the bearing body can move, is provided, and by the flat iron brackets b. is attached to the hanger g ² g ^{2 of} a carriage. The constructions of the traverse, the hanger, etc., show the construction of the patents no. 2934 and No. 22,888 known arrangements.

Do the circumstances dictate that the movements of the clamping jaws of the coupling apparatus are not as in those previously described? Arrangements, Fig. 1 to 16, in the vertical, but perpendicular in the horizontal direction to the pull rope, the apparatus can now be described in the Be modified wisely.

The modification shown for this arrangement in FIGS. 17, 18 and 19 (in FIG. 19 the one jaw K with the associated sector is not shown) is analogous to the arrangement illustrated by FIGS The entire apparatus is now in a horizontal position, except that the jaws K and K ^J are pressed against the rope simultaneously by means of the two eccentrically shaped segments TT ¹ and therefore not only the outer jaw K ¹ but also the inner jaw K with it a slot P ^ and therefore also the slide B is provided with a guide pin q ² . Furthermore, the housing cover lying between the jaws and the lever is BEZW. the lid part Q. ¹ , as well as the housing G itself designed in the shape of a ring groove and stored in the bearing body U, which in turn is fastened to the wagon hanger in a known manner by means of flat iron brackets b. !

In the arrangement shown in FIGS. 22 and 23, the inner jaw K, analogously to FIGS. 13 and 14, is pressed horizontally outward against the pull cable by the eccentric segment T , while the outer clamping jaw K ^l is vertical in the housing standing rollers JR ' ² R ² slides.

The release of the bolt L to fix the two jaws KK ¹ is effected by the pin M ² located on the eccentric E, which presses against the nose O of the bolt L at the given moment, while after the eccentric E has been moved back (see those in dotted Lines drawn position) the spiral spring S ¹ prefst the bolt L against the backet ¹ and pushes between the approaches PP as soon as the latter are in the middle position, Fig. 19.

Fig. 24 to 33 also illustrate such a coupling apparatus in a horizontal arrangement. In this, the clamping jaws consist of two indefs completely separate and independent of each other acting jaw pairs KK ¹ and KK ^l. The former come into effect when the carriage is pulled by the pulling rope in the direction of movement, and the latter when the carriage tends to move ahead of the rope, Fig. 29.

The two pairs of jaws are again BEZW by tooth-shaped incisions. Projections V ¹ V ² , Fig. 33, connected to one another in such a way that when the jaws move in the direction of the rope, one part K must follow the associated K ¹ and the other part k must follow the associated / c ^1. The jaws are pressed together by the rollers R ³ i? ^3, the / move against the inclined surfaces Z ^{1. 2} The jaws K and k are guided in the housing by the guide strips X ¹ X ² , which move in corresponding recesses in the housing cover t ^l r ^x , FIGS. 25 and 28.

The engagement and disengagement of the apparatus respectively. the movement of the front jaws K and k normal to the rope is controlled by eccentric J? ¹ and the push rod B ¹ causes. The latter is firmly connected to the cast iron head piece G ¹ , so that when the push rod B 'moves forward, the head piece G ¹ with the jaws K and k are also forced to participate in this movement.

The actual housing G ² is shaped in a manner similar to that of the apparatus in FIGS. 17 and 19, namely it can move in the form of a ring groove in the bearing body U ¹ , which is connected to the trolley suspension by means of the bracket bb, FIG. 30 .

The re-adjustment of the pairs of clamping jaws in their middle position happens at this apparatus in the following way:

The two inner clamping jaw halves K ¹ and k ^l carry the approaches ^ ¹ ^ ² below, while on the push rod JB ¹ the wrought iron

Claims (4)

Plate P ¹ is attached to the guide strips / ¹ Z ^2. When the apparatus is opened by turning the eccentric E ¹ and moving the push rod B ¹ forward, with the clamping jaws Kk shifted to the side, the plate P ¹ with its inclined strips Z ¹ P comes into contact with the correspondingly inclined projections ^ ¹ Jj ^{2 of} the clamping jaw halves K ¹ k ^l thus forcing the latter to return to their middle position. ^{The bolt JL 1} , which is arranged in the same way as described in FIG. 19, is again used to lock the clamping jaws in the middle position. The two pairs of jaws KK ^λ and kk ¹ are held together here by the fork u ¹ , FIG. 29. 32 shows the clamping jaws with the projections ■ { ^λ \ ² in the middle position and with the apparatus closed and the position of the push rod corresponding to this position with the inclined guide strips I ¹ I ² . 31 shows the jaws in the closed position; the one. Jaw pair KK ¹ is pulled out to the outermost limit, while the other pair of jaws is still in the middle position. Finally, FIG. 33 shows the clamping jaws in the open state and locked in their central position ^{by the bolt L 1.} The forward movement of the push rod B ¹ forced the pair of jaws, which had previously been pulled out to the outermost limit, to return to its middle position. The two rollers RR ¹ , which can move freely around the pins w n> ^x, serve to guide the pull rope Z. The latter are firmly connected to the housing G ² and simultaneously serve as a guide for the front head piece G * during its forward movement, FIG. 29.
